Have real nurses on allnurses.com tried and tested the system, and found all the claims in the advertisements to be true?

In case of a nurse who wants to find out whether or not legal nursing is the right fit, it is realistic/practical to spend that amount of money for the certification?

As a nurse in this economic climate - where job security is no longer the highlight of the profession - is it feasible to exhaust hard-earned savings (however meager) just to keep alive the dream of a better tomorrow?
